FAN ATTACHMENT FOR CHAIRS.

Specification of Letters Patent.

Patented May 21, 1907'.

Application filed May 26,1906- Serial No. 318,973.

in Fan Attachments for Chairs, of which the following is aspecification.

This invention relates to fans designed especially for use on rockingchairs, and has for its objects to produce a comparatively simple,inexpensive device of this character which may be readily installed foruse, and one wherein the fans chair.

A further object of the invention is to provide a device of thischaracter embodying an oscillatory fan-carrying shaft, adapted forattachment to the chair, one wherein the shaft will be positively movedin one direction when the chair is rocked and automatically rotated inthe opposite direction during forward movement of the chair.

With these and other objects in view, the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings: Figure 1 is a perspective view of a chairequipped with a plurality of fans embodying the invention. Fig. 2 is aside elevation of the same. Fig. 3 is a detail, sectional view of one ofthe side fan operating shafts, the section being taken centrally andlongitudinally through the shaft. Fig. 4 is an elevation on an enlargedscale of one'of the shaft-operating springs. Fig. 5 is a perspectiveview of one of the bearing brackets.

Referring to the drawings, 1 designates a rocking chair of the usual orany appropriate construction and material having rockers 2., andcomprising a seat 3 and a back 4, which latter includes vertical sidemembers or styles 5 extended downward below the seat 3 to form rear legs6 connected at their lower ends to the rockers 2.

Fixed to each of the standards 5 is a bearing member or ring 19 in whichis journaled for rotation a side fan-operating shaft 20 provided at itsupper end with a forwardly extending arm 21 carrying a fan 22 and havingat its lower end a tubular portion or section 23 in which is arranged aspiral spring 24 will be automatically actuated during the rockingmovement of the that the shaft will,

fixed at its upper end to the shaft and at its lower end to a relativelymovable pin 25 projected downward through a cap 26 fitting on the lowerend of the shaft, the pin, which is adapted for rotation relative to theshaft, be-

ing of square or other non-circular form and adapted to fit in acorrespondingly shaped? opening 27 provided in the bearing bracket 28attached to the seat 3 and having at its rear end a pair of spacedvertical ears 29 in which is journaled aguide pulley 30 on which isarranged for travel aflexible traction cord or connection 31 having itsupper end, which is wrapped or coiled a number of times around the shaft20, terminally engaged with the latter and its lower end attached to thevertical portion or arm 32 of an operating spring 33 provided with asubstantially horizontal forwardly extending arm 34 fixed to the adjacent rocker 2, the arm 32 being arranged for vertical movement in aguide 35 fixed to the rocker.

In the operation of the device, when the chair is rocked rearwardly thespring 33 com ing in contact with the floor surface moves the portion orarm 32 upwardly, thereby slacking the connection 31 and allowing theshaft 20 to rotate in one direction under the influence of spring 24,the cord 31 being at the same time wound upon the shaft. As the chairrocks forwardly the spring 33 in again expanding moves the portion orarm 32 downward and exerts traction on the cord 31 for rotating theshaft 20 in the opposite direction, it being understood that the spring33 is of a strength sufficient to overcome the tension of spring 24while rotating the shaft against the action of the latter, and further,

during the rocking motion of the chair, be continuously operated foractuating the fan 22.

Having thus described my invention, what I claim is:

1. A fan attachment for rocking chairs comprising a rotary operatingshaft having a tubular portion, a spring arranged in said portion andconnected for rotating the shaft in one direction, a second springattached to the chair rocker and having a vertically movable arm adaptedfor reciprocation during rocking motion of the chair, and a flexibleconnection engaged with said arm and with the shaft, said connectionbeing wound on the shaft and adapted for rotating the same in onedirection against the action of the first named spring.

2. A fan attachment for rocking chairs comprising a rotary operatingshaft, a spring operatively connected With the shaft for rotatingi thesame in one direction during rearward movement of the chair, a secondspring having an arm adapted for reciprocation during rocking motion ofthe chair, and a connection between said arm and shaft for rotating thelatter in the other direction against the action of the first namedspring.

3. A fan attachment for rocking chairs comprising a bearing attached tothe chair and provided with a non-circular opening, a rotary fanoperating shaft sustained on the chair and having a tubular portion, aspring arranged in said portion and connected at one end with the shaft,a pin rotatably mounted in the tubular portion and engaged with theother end of the spring, said pin having 'a non-circular portion fittedin said hear ing opening for rotation relative to the shaft, a secondspring attached to the chair rocker and having an arm arranged forreciprocation during rocking movement of the chair,

and a connection between the arm and shaft for rotating the latteragainst the action of the first named spring.

In testimony whereof, I afliX my signature in presence of two Witnesses.
